ZIP 18330 vs ZIP 18331

This side-by-side compares ZIP 18330 (Effort, PA) and ZIP 18331 (Gilbert, PA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 18330 has a population of 8,927 at 210 people per square mile, while ZIP 18331 has 867 at 98 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 18330 reports a median household income of $93,733 against — in ZIP 18331, with per-capita income of $39,053 vs $46,824. The share of adults holding a bachelor's degree or higher is 24.7% in 18330 and 9.3% in 18331. Poverty rate reads 4.3% vs 11.5%, and unemployment 7.0% vs 29.3% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $291,600 in 18330 versus $281,900 in 18331, with median rent of $1,348 and $1,257 per month respectively. Homeownership rate is 94.1% vs 69.2%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
